<h2>NCI 60 Data

</h2>

<h3>Description</h3>

<p>NCI microarray data. The data contains expression levels on
6830 genes from 64 cancer cell lines. Cancer type is also recorded.

</p>


<h3>Usage</h3>

<pre>NCI60</pre>


<h3>Format</h3>

<p>The format is a list containing two elements: <code>data</code> and
<code>labs</code>.
</p>
<p><code>data</code> is a 64 by 6830 matrix of the expression values while
<code>labs</code> is a vector listing the cancer types for the 64 cell lines.
</p>


<h3>Source</h3>

<p>The data come from Ross et al. (Nat Genet., 2000). More information can be obtained at
